METHOD FOR THE FORMATION OF SLIDING SURFACES WITH A UNIDIRECTIONAL PREDOMINANCE, DEVICE FOR ITS IMPLEMENTATION AND ITS APPLICATION TO SKIS

摘要

Skis. /P P In the profiled surface of the object, partially overlapping profiles are hollowed out by surfacing and forming, in the longitudinal direction, stepped sawtooth ramps, by moving the position of the tool of cutting in the longitudinal and transverse directions of the surface, with steps defined in the transverse direction and in the longitudinal direction as well as with an offset of the successive transverse rows, at the rate of a fraction of the step width in the transverse direction. Sliding surface of skis or other elongated objects which should preferably be able to slide in one direction.
